hi i have a 93 z28 and i did the ls1 swap to it. does any one know how to get my old lt1 gauges to work with my ls1 set up? i would be really thankfull for some answers.

 

Oil pressure gauge will work fine. The temp gauge will need a three pin sending unit from a 98(will have to run extra wires), and the tach will work fine after the ECM is reprogramed for the right number of pulses per revolution.
